Not all eco-friendly undies are created equal. When it comes to softness, breathability, and sustainability, the debate often boils down to bamboo vs Lenzing Modal underwear. Both sound green, both feel good—but one comes out on top.

At Nat'v Basics, we made our choice clear: Lenzing Modal™. Here’s why it wins the comfort and conscience game.

What Is Bamboo Fabric?

Bamboo is a fast-growing plant, and in theory, it’s a dream for sustainability. The fabric made from bamboo is marketed as natural and eco-friendly. But what most people don’t know is that it requires heavy chemical processing to transform the plant into something soft enough to wear.

Key pros:

• Renewable resource

• Naturally breathable

But the cons?

• Often involves toxic solvents

• Less transparency in production

• Quality and softness can vary drastically

Not exactly the clean green image we’re led to believe.

What Is Lenzing Modal?

Lenzing Modal™ is made from sustainably sourced beech trees. Unlike bamboo, its entire production process is traceable, ethical, and closed-loop — meaning water and solvents are reused instead of wasted.

Why it’s better:

• Ultra-soft feel (seriously, the softest fabric for underwear)

• Breathable underwear material

• Certified by EU Ecolabel for sustainability

• Less water + energy used in production

That’s why it checks every box for eco-friendly underwear fabrics.

Comfort Test: Modal Wins Hands Down

Sure, bamboo feels nice. But Lenzing Modal™ takes it further:

• Smoother against the skin

• Holds shape better after washing

• Less pilling over time

• Feels cooler in warm weather

If you’ve got sensitive skin, Lenzing Modal is the best fabric for sensitive skin — it’s hypoallergenic and non-irritating.

Breathability & Moisture Control

Both fabrics claim breathability. But Modal is the one that delivers consistently.

• Moisture-wicking for all-day freshness

• More airflow = less sweat

• Feels dry, even on humid days

If you’re after breathable underwear materials, Modal’s structure naturally supports air circulation.

Sustainability Score: Transparency Matters

Here’s the deal: bamboo might start sustainable, but its journey to fabric can be anything but. With Modal, you know exactly what you’re getting. Lenzing is transparent about every step.

Nat'v chooses Lenzing Modal™ because it offers:

• Forest-to-fabric traceability

• Certified sustainable forestry practices

• Closed-loop production (nothing wasted)

If you care about sustainable women’s underwear, this matters.

Why Nat'v Says No to Bamboo and Yes to Modal

We tested both. And while bamboo sounds great on paper, Lenzing Modal simply performs better in real life:

• Feels softer and holds up better after multiple washes

• Wears cooler, especially in Aussie heat

• Safer for your skin, with no chemical surprises

• More sustainable, without greenwashing

That’s why every Nat'v Basics piece is made with Lenzing Modal™. We’re here for real comfort and real impact—no fluff.
